Windows Vista Vista random feeze

its really odd, it either freezes in the 1st hr or two or doesn't at all.

sometime PC runs for days if not weeks and i have no problem but when i reboot, it will freeze with in the hr (today it froze 4 times already most with in minutes of reboot)

this is same PC >> http://www.windowsbbs.com/windows-vista/88453-vista-registry-clean-up.html ( I was hoping the problem was solved)

I know i have all the latest drivers Ive been checking regularly, although i still have some doubts about the USB driver.

i also thought it might be malware, but i have:
Windows defender
AVG free
and SpywareBlaster for extra protection
all fully updated

I tried disabling the start up components in MSConfig (no result)

I realy dont know what to try next.

 

Yes Steve, because the possibilities are endless i nerver git the courage to tackle that problem head on.

What application are you using when it freezes? Is it always the same app?
FireFox, is on 24/7 on the PC.

 

either facebook.com (new to this site)
or astroempires.com (been on there for years, my xp machine had no problems with ff)

mostn if not all the times i have
1st tab igoogle
2nd tab gmail
3rd tab astroempire
4th tab facebook (mafia wars)
5th tab facebook (all over)

allot of times freeze happened right after i click a link in Astroempires, or in the Mafia wars app.

 

since FF is the main suspect, here is some additional info:
I use version 3.5.5, have it set to auto update since day one.

Add-ons installed:
- adblock plus v. 1.1.1
- AVG safe search 9.0.0.701 (i upgraded to AVG 9 the day before i started this thread)
- Dictionnaire Hunspell (French) v2.1
- Download StatusBar
- FEBE 6.3 (i got this one when i was doing my post ff 64 cleanup the thread mentioned in 1st post)
- ForecastFox
- GreaseMonkey
---(scripts for GM)
---AE trade helper (will add url for script if needed)
---AE Helper CP V4.884 (will add url for script if needed)

Edit: after posting the above i decided to make a small test.
around noon i restarted my PC, and instead of starting FF directly i decided to wait, so i launched Chrome instead and went about my normal business (same sites as usual, but with fewer tabs open) about 45 minutes later i quit chrome and launched FF (starting a new session, instead of restoring the previous one) its almost 3pm and PC did not freeze yet.

dose that help in anyway?
